Is that person still you or just your cells remade as a different person who looks like you and thinks like you.
This is another problem with teleportation. Sure, we could transfer the physical body, but will the transfered brain have the same thoughts, memories etc. as the one before the teleport?
I guess that if we wanted to achieve this, we would have to first find a way to digitalize our consciousness, send the data to the place where we would teleport and then let it be un-digitalized and put back into our body.
Ignoring the whole destroy one body make another theme the idea of teleportation isn't at all possible with the current model of physics that we know.
It's impossible for anything that contains mass to reach the speed of light, this is due to mass increasing as speed increases (only noticeable once you achieve 10% of the speed of light) so to accelerate to the speed of light mass would increase to infinity.
This ain't really discussion material, the science behind it is impossible so unless we're completely wrong about physics teleportation is not possible.

Just gonna comment on this, our thoughts, memories, and stuff are all stored in the nerve connections in the brain iirc, so they are still a part of our physical body.

If a time machine were to ever be invented, we would already have it. Unless parallel universes are a thing, of course.
